Penelitian ini bertujuan untuk meningkatkan kapabilitas akademik siswa dan guru melalui program pembinaan olimpiade yang mencakup diskusi soal-soal olimpiade, pelatihan bagi guru, serta evaluasi efektivitas kegiatan. Kegiatan dilaksanakan secara daring melalui Zoom Meeting pada 19–20 April 2025, dan diikuti oleh 46 peserta dari mitra, yaitu SMA AQL Islamic School 2 Purwakarta, yang terdiri atas siswa kelas X–XII dan guru pendamping. Metode pelaksanaan menggunakan pendekatan interaktif berupa pemaparan materi, simulasi soal, serta diskusi terbuka dengan topik meliputi Geometri, Aljabar, dan Teori Bilangan. Evaluasi dilakukan melalui post-test dan angket kepuasan untuk mengukur pemahaman peserta dan efektivitas program. Hasil evaluasi menunjukkan bahwa 89,1% peserta mengalami peningkatan pemahaman terhadap materi, dan 93,4% menyatakan puas hingga sangat puas terhadap pelaksanaan kegiatan. Selain itu, 89,1% peserta menilai webinar ini sangat bermanfaat dalam memperluas wawasan dan meningkatkan kesiapan menghadapi kompetisi. Dengan demikian, program ini terbukti efektif dalam meningkatkan kapasitas akademik siswa dan keterampilan guru dalam membimbing peserta olimpiade, serta memberikan kontribusi positif terhadap peningkatan kualitas pendidikan matematika di tingkat SMA.Abstract: Many senior high schools still face challenges in preparing students and teachers for mathematics olympiads. This study aims to enhance the academic capacity of both students and teachers through a training program that includes problem-solving sessions, teacher workshops, and evaluation of program effectiveness. The activity was conducted online via Zoom Meeting on April 19–20, 2025, involving 46 participants from a partner school, SMA AQL Islamic School 2 Purwakarta, consisting of grade 10 to 12 students and accompanying teachers. The program applied an interactive approach, including lectures, problem simulations, and open discussions covering Geometry, Algebra, and Number Theory. Evaluation was carried out through post-tests and satisfaction questionnaires to measure participants' understanding and the overall effectiveness of the program. The results showed that 89.1% of participants experienced improved understanding of the material, and 93.4% expressed satisfaction with the implementation of the activity. Additionally, 89.1% of respondents found the webinar highly beneficial in broadening their knowledge and increasing their readiness for academic competitions. Therefore, this program proved effective in improving both student competencies and teacher mentoring skills, while also contributing positively to the quality of mathematics education at the senior high school level.]]>
